AUR9717 - 1.5MHz PWM Step-down DC-DC Converter

Description

The AUR9717 is a high efficiency step-down DC-DC voltage converter.

The chip operation is optimized using constant frequency, peak-current mode architecture with built-in synchronous power MOSFET switchers and internal compensators to reduce external part counts.

Features

  • including Soft Start (SS), Under Voltage Lock Out (UVLO), Input Over Voltage Protection (IOVP) and Thermal Shutdown Detection (TSD) are integrated to provide reliable product.

Data Sheet Dual 1A, 1.5MHz PWM Step-down DC-DC Converter with OVP AUR9717 General Description The AUR9717 is a high efficiency step-down DC-DC voltage converter. The chip operation is optimized using constant frequency, peak-current mode architecture with built-in synchronous power MOSFET switchers and internal compensators to reduce external part counts. It is automatically switching between the normal PWM mode and LDO mode to offer improved system power efficiency covering a wide range of loading conditions. The oscillator and timing capacitors are all built-in providing an internal switching frequency of 1.5MHz that allows the use of small surface mount inductors and capacitors for portable product implementations.
